SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 257,006, dated April 25, 1882.

Application filed February 2-1, 1882. (No model.) I

To all whom it may concern:

Be it known that I, ALFRED S. HENN, a citizen of the United States, and resident of New Haven, in the county of New Haven audState of Connecticut, have invented a new and valuable Improvement in Bolt Snap-Hooks; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 is a side view of the bolt snap-hook. Fig. 2 is an edge view of the same. Fig. 3 is a sectional view. Fig. 4 is a view of the capplate, and Fig. 5 is a view of the body-plate with the cap-plate removed.

This invention has relation to bolt snaphooks; and it consists in the construction and novel arrangement, in connection with the curved bolt and its spring, of the circularlygrooved body portion and the circularlygrooved cap-plate eomplemental thereto, and forming a circularly-curved recess to receive the bolt and spring, all as hereinafter set forth.

In the accompanying drawings, the letter a designates the body portion or main casting, which is formed with the hook I) and loop 0, and between the two a halved or thinner por tion, d, which is circularly grooved at c, and is provided witharivet-seat,g. The outeredge hofthe groove 0 in the portion nearest the hook is east short.

k represents the cap-plate, which is similar in shape to the halved or thin portion d of the body, and is designed to fit neatly thereon, filling the recess out, so that each side of the body will present a smooth exterior surface of similar appearance. In the cap-plate is formed a circular groove, 6, which is complemental to l the groove 6 of the body, and is designed to form therewith a circular recess, in which is placed the spring 8 and the curved bolt 7c. The outer edge of the groove 6 of the cap-plate is cast short at h, opposite to the short portion h of the wall of the groove in the body, and when these short edges are approximated a slot, m, is formed, in which moves the neck of the thumb-stud l.

The cap-plate is secured to the body of the book by means of a rivet, r, passing through the holes or seats g and g. 7

In this construction no bending is required after the hook portion is cast. The book can therefore be cast in strong form, as it is not liable to be broken in introducing the spring and bolt.

At the end of the boltrecess an apertnre,z, is provided to afford an outlet to water, which sometimes may enter the recess.

A spring and bolt-holding body made in two parts are not new in a snap-hook, and are not broadly claimed herein.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

A bolt snaphook consisting of the circularly-grooved body portion a and the complemental circnlarly grooved cap-plate h, riveted thereto, and iorming therewith a circular recess to receive the curved bolt and spring, substantially as specified.

In testimony that 1 claim the above I have hereunto subscribed my name in the presence of two witnesses.
